Flat & Membrane Roofing
Waterproof membrane systems engineered for flat and low-slope roofs across Central Ohio.
WHY CHOOSE KMC FOR
FLAT & MEMBRANE ROOFING
Flat and low-slope roofs require specialized systems that asphalt shingles simply can't provide. Without proper drainage and waterproofing, flat roofs are highly susceptible to ponding water, leaks, and accelerated deterioration.
KMC Roofing Co. installs and repairs TPO, EPDM, and modified bitumen membrane systems for commercial buildings, apartment complexes, and residential additions with flat roof sections. These systems are engineered for maximum waterproofing and long-term durability.
Our crews are trained and certified in flat roofing installation, and we understand the unique challenges of Ohio's freeze-thaw cycles and heavy precipitation on flat roof systems.

COMMON QUESTIONS
TPO (Thermoplastic Polyolefin) is a white, heat-welded membrane known for energy efficiency and durability. EPDM (Ethylene Propylene Diene Monomer) is a black rubber membrane known for flexibility and longevity. Modified bitumen is an asphalt-based system that's been reinforced with modifiers for improved performance. We'll recommend the best option for your specific application.
With proper installation and maintenance, TPO and EPDM systems typically last 20–30 years. Modified bitumen systems last 15–20 years. Regular inspections and minor maintenance can significantly extend these lifespans.
Yes. Ponding water (water that remains 48+ hours after rain) accelerates membrane deterioration and can lead to structural problems. We can assess your drainage and recommend solutions, which may include adding drains, adjusting slope, or applying a new membrane.
Often, yes. If the underlying insulation and decking are in good condition, we may be able to repair or re-coat the existing membrane rather than doing a full replacement. We'll assess and give you an honest recommendation.
Yes. We service commercial buildings, apartment complexes, HOAs, and any structure with a flat or low-slope roof section.
